b413f3da26 ELF shared library: PT_NOTE can prevent packing 
Android build environment post-processing is adding a PT_NOTE
("Android", 21, "r16-beta1") at the high end of PT_LOAD[0],
above the stub; the runtime linker looks there before de-compression.

402c885987 Merge branch 'jreiser-elfstub' into devel 
New stub strategy on Linux:  Linux adds too many other segments
to the address space: [vdso], [sigpage], ...; and qemu might
arrange them differently.  Thus the only reliable mappings
are the PT_LOAD of the compressed file itself; all other
address space is unknown!  First, the compressed file uses
.bss to occupy all unused pages up to the original brk(0).
Then at run time, the stub gets another mapping of /proc/self/exe,
and uncompresses the user program on top of the original pages.
[*BSD unchanged for now?]
